To all 207mm z 't may concern.' j

Be it known that I, BOYD VILIIE, a citi@ zen of the' UnitedStates of America, residing .at Mount Vernon, lVestchester County, w\Iew York, have invented anew Yand useful Sprinkler for Filtering Systems,

etc., otwhich the 'following is a specification. My invention relates to. certain new and ing sewage.

In many sewage dlsposal works, it is customary, 1n order to prevent pollution of streams, to filter the sewage water, and this is accomplished by discharging the sewage water upon a filtering bed,` by means of which, the ltering action is secured, so that the water discharged into a stream will be free from pollution.

In my former Patent #968,015 of Au#` gust 23,1910, I have disclosed an improved means for splashing or spraying the water of a substantial area, and the present in-V vention constitutes an improvement 1n that V part of the apparatus.

In the accompanying drawings: Fig. 1 is a sectional view of part of a .filtering tank such as employed in a sewage purification system showing my apparatus in operative position. l Y

Fig,'2 is a relatively enlarged vicw of the principal parts of my invention, partly in elevation, and partly in section.

Fig. 3 isa longitudinal section of one detail. Y v v l i Fig. 4 is a longitudinal section of the same detail taken in a plane at` right angles to the plane ofthe section shown in Fig. 3

a, represents the wall of a filtering tank in which the filtering bed c vis located. The particular formation of the filtering bed is immaterial to this invention, it beingl ordinarily composed of a proper material to obtain the desired ltering action. The

filtering tank, of course, is provided with suitable air pipes and drain pipes, the sameV being customary and requiring lno description herein.V The sewage water is brought into the iiltering tank by-means of a. suitable pipe which in this particular instance, runs below the surface of the filtering material c, and which is extended throughout the filtering bed so that spraying nozzles may be attached thereto at intervals in such a manner that the sewage water will be sprayed Yover substantially all of the bed,

so that the action willbe-uniform and 4most eicient. In: the drawings, I have illustrated in position only one of. these nozzles, and this I will now describe. v. b2, is a pipe which taps into the supplypipeb and projects rip-+5 wardly a proper distanceA above thebed of the ltering material. -Mounted at the end Y of this pipeismy new and improved sprayuseful spraying apparatus, particularly use-) ful 1nv connection with apparatus for filtrering'pplevice which is constructed in novel manner so as to possess a number of marked advantages vheretofore unattained in devices of this character. The spraying device comprises what I will term a head cZ. This is suitably secured to the upper end ofV the pipe b2. The head d, is provided with two spaced water passages af (Fig. 3). The partition e between these passages is what. I will term` a breaker. This breaker in crosssection is bestseen inl Fig; 3, audit will be notedthat the lower edge thereof is rela tively sharp for the purpose hereinafter described. f is an outlet. g is a nipple arranged to screw onto the outlet end of the Abody* d, said nipple being provided with a central opening'of lthe desired slze; 71. 7is a deflector arranged directly above the outlet. Y

This `deiiector is generally cup shaped as shown, and is adjustably mounted upand down upon the threaded stem or support el.

This stem or support z' may be threaded into the upperend of the breaker .e so that it will pass centrally Vup through the outlet, thereby holding the deilector It centrally kwith relation .to the discharge of yfluid through the outlet. h is a lock nut on the threaded stem for locking the detlector-'tV in the desired Vposition of adjustment.

In operation, the sewage water is drivenk throughv the head d, and is deflected in opposite directions through the branch passages 2V-d. Above the breaker,l the sewage waters come together so as to Vbe discharged through the outlet in an upward direction, and so as to impinge against the underside of the dellector h and be thereby broken up into spray and deflected laterally over a substantial area, theY area being varied accord-V ing to thegwater pressure and according to the adjustment of the deilec'tor 7L on the stem z'. VIf there should be any solid particles in the water these will tend to be broken up by coming in 'contact with the relatively sharp lower edge of the breaker e, so that dan er of clogging the outlet is practically ehm-l inated. i v

I have shown my inventionin its preferred invention is particularly applicable for the.

use described herein,y Ido not care to limit myselfto this 'use exclusively since there may be many other connections in which such a spraying apparatus may be employed with great; satisfaction.

What I claim is Y 1. In a spray device of thel character described, a main body portion ladapted for attachment to ya pipe and comprising, an outer shell and a partition within said shell dividing the klatter 'into two spaced apart curved ducts merging into each other above andbelowthe partition, said partition being relatively sharp on the lower side `for breaking Lup. :solid matter carried by the .Huid

through said body portion, a central stem Vsecured tosaid partition land passingupwardly through the outlet end of said Lbody portion, anda deiector adjustably mounted on said central stem fordeeetingftheiiuid passing lthrough said body portion.

2. In a combinationasdened inclaimvl, *Y and a removable cap onthe outlet end of said body portion .and havingan aperture therethrough whereby the `flow of liquid through lsai ilbody portion willbe restricted.A
